About the Airtac GAFC Air Service Unit GAFC600C20SK
This GAFC600C20SK is an F.R.L. combination built from a filter-regulator and a lubricator on one T-shape bracket. The 3/4in port and 3430 g mass put it in the largest GAFC size class, meant for a machine header or multi-station line rather than a single actuator. Air is filtered and set to pressure in the first body, then the lubricator adds a metered oil mist last, so oil never travels back through the regulator seat.
The metal bowl is specified by the C code, and the common specification of 1.0 MPa max pressure and -5 to 70 C applies to all bowl materials. The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element. The 205 cc condensate bowl and 410 cc oil bowl are both fitted, and the circular gauge reads in MPa and psi for the default PT thread.

Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Where the Airtac GAFC Air Service Unit GAFC600C20SK Is Used
Machine Tool Header
Feed a CNC lathe or milling machine header with 3/4in supply, where the 410 cc oil bowl supports continuous lubrication for multiple actuators and the 205 cc condensate bowl reduces maintenance frequency.
Multi-Station Assembly Line
Supply a multi-station assembly conveyor where several workstations draw from one F.R.L. set, and the large bowls mean fewer line stoppages for servicing.
Heavy Press Lubrication
Serve a stamping or forming press that needs regulated air at 0.15-0.9 MPa and consistent oil mist for pneumatic clutches and cylinders, with the 3430 g unit mounted on a proper frame.
Is the Airtac GAFC Air Service Unit GAFC600C20SK the Right Air-Prep Unit?
Choose the GAFC600 when a 3/4in port and the largest bowl capacities are needed for high-demand lines. The metal bowl is the only option for this body, and the standard type is the only pressure range offered. The semi-auto drain dumps condensate on each pressure drop, while the manual drain gives on-demand control. The 40 um element is the standard grade, and the circular gauge is fitted with an MPa/psi scale for the PT thread. The reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue. Spare parts are orderable as GAFR600-20 and GAL600-20, both with the same body and port. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan for a supply near the maximum if you need the full regulated output.
Quick checklist
- ✓ Body size for your peak flow (3/4" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: Metal (C) only
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Thread & gauge scale (PT / G / NPT)
Installation & Maintenance Notes
- check Install with the airflow arrow: filter-regulator first, lubricator last.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Fill the oil bowl with ISO VG 32 or equivalent only.
- check Drain condensate before the 205 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 3430 g unit on its bracket, not on the tubing.
The lubricator adds an oil mist downstream of the regulator. If any part of the line must stay oil-free, use a plain GAFR600-20 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC600C20SK FAQ
The GAFC600C20SK operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C. It has a 205 cc drain bowl and a 410 cc oil bowl, weighs 3430 g, and uses ISO VG 32 lubricant. The element grade is 40 um.
The metal bowl is the only bowl option for the GAFC600 body, as specified by the C code. The catalogue lists the same 1.0 MPa max pressure and -5 to 70 C temperature range for all bowl materials, so the metal bowl is a build choice rather than a performance upgrade. Confirm it suits your specific environment, as the catalogue provides no material-specific chemical or impact data.
